CAR TRUCK.

Application filed A rn e,

To aZZ 1071 am it may concern Be it known that I, HERMAN C. Pnrnnn, a citizen of the United States, residing at Blue island, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car Trucks, of which the following is a full, clear, concise, and exact description.

My invention relates to car trucks and has a number of objects and advantages in view. V V

In accordance with one characteristic of my invention the journal boxes are formed with displaceable longitudinal walls, preferably the bottom walls, readily permitting disassembly of the car wheel axles from the balance of the truck, the ends of the axles being preferably adapted for passage through the opened bottoms of the journal boxes.

The fixed portions of the journal boxes and the side frame are preferably formed in one integral casting of iron, preferably steel, and the arch bar is formed of rolled iron, preferably steel and .is united at its ends with the ends of the top of the cast side frame without bolts or rivets.

I will explain my invention more fully by reference to the accompanying drawings in 30 which Fig. 1 is a view in side elevation, partially in section of a car truck made in accordance with the preferred embodiment of the invention, parts also being broken away; Fig. 2 is a view from above of the truck l. portion shown in Fig. 1, parts being shown in section and parts being broken away; Fig. 3 is a sectional view on line 3-3 of Fig. 1; Figs. 4t and 5 areviews of the structure appearing in Fig. 3 with parts rearranged; and F ig, 6 is a perspective view illustrating a journal box and its bottom 'wall in separated relation.

Like parts are indicated by similar characters of reference throughout the different figures.

The drawing shows a two wheel portion of a four wheel truck, the car wheels 1 and 2 being upon ends of axles 3 with reduced bearing portions l whose other ends have similar wheels thereon. Each end of each axle supports a bearing 5 which carries a wedge 6 on which is supported the top wall 7 of a car axle box.

The top or head 8 of the T-shaped cast iron or steel side frame is preferably of against the bottom ends purpose, it being made 1921. Serial No. 458,998.

channel formation, the ends of this side frame as well as the entire side frame top being formed integrally with the top walls 7 of the journal boxes and preferably also with the side walls 9 of the journal boxes.

The depending bifurcated stem 10 of the T-shaped side frame has a large opening between its sides and at the top of which is dis posed the truck bolster 11 that is supported by the springs 12 whose top ends engage the bottom of the truck bolster and whose bottom ends rest upon a channel iron girder 13 extending between and uniting the two side frames of the truck, preferably by being riveted to the two sides of the bifurcated stem 10 at the bottom ends thereof that are thereby joined.

The arch bar l i is preferably formed of rolled iron, desirably rolled steel, and is of semidiainond shape, being downwardly depressed to be received beneath the ends of the stem 10, the arch bar being riveted of the sides of said stem and engaging the bottom of the girder. Said arch bar is preferably formed with depending hooked ends 15 that are surrounded at the bights of the hooks by the metal of the east side frame, these hook ends being preferably received within the channel of the side frame top 8. In the preferred embodiment of the invention the arch bar is placed in the casting mold so that the cast metal will form in place about the bight portions of the hooked ends of the arch bar whereby a substantially integral structure is formed comprising the cast metal side frame, the rolled metal arch bar and the cast top and side wall portions of the journal boxes.

The side frame serves as a compression member, being especially adapted to serve this purpose by being formed of cast iron, preferably cast steel.

The arch bar 14 serves as a tension memher, being especially adapted to serve this of rolled iron, preferably rolled steel.

The portion of the structure herein disclosed that relates to the cast sideframe and the rolled arch bar is broadly covered by my co-pending application Serial No. 458,- 997, filed April 6, 1921, there being certain departures from the construction disclosed in said co-pending application that are herein claimed.

An important characteristic of my pres- "ner or rear side of the journal box.

ent invention resides in the construction of the journal box irrespective of the nature and construction of the side frame and arch bar and-the manner of their assembly with each other and with the journal boxes. This portion of my invention resides in forming the journal box bodies with displaceable longitudinal walls which, when displaced, permit of the lateral separation of the axles from said boxes. The longi tudinal box body walls that are thus displaceable are preferably the box bottoms which are readily removable after the truck frame is lifted. In the preferred manner of carrying out my invention, the side walls of each box body are formed with inwardly projecting ledges'16, which support the corresponding box body bottom wall 17 Such wall desirably has upward side continuations 18, an upward rear hollow continuation 19, and an upward forward continuation 20, these four upward continuations and the bottom wall from which they rise constituting a trough for holding the oil containing cotton waste or packing which lubricates the corresponding axle end in the zone ofthe bearing 5. A suitable dust guard 20 is assembled with each journal box above and contacting with the axle. Another suitable dust guard 21 is held in the interior of the hollow wall 19, both dust guards substantially surrounding the corresponding axle end and making the journal box having them substantially dust proof upon the in- Any usual or suitable lid 22' is provided upon the front of each box, the lid shown being hinged upon the top front edge of the top -wall of a box body.

The side walls 9 of each box body are desirably joined by a front box body wall .portion 23 that slopes downwardly and rearwardly and serves normally to prevent the bottom of the box from being dislodged in a forward direction. The downward continuation of the dust guard frame 25 prevents rearward displacement of the box bottom.

A foot 26 is cast upon the front wall portion 23 for engagement by a lifting jack by means of which any journal box may be lifted to free the bearing 5 and the wedge block 6. When this block and hearing are removed the corresponding axle end -may be eased into the position shown,

whereupon the trough bottom of the box may be moved upwardly and forwardly (Fig. 5) whereafter the axle and box may be separated. After the necessary adjustments or repairs have been made the trough bottom of the box may be restored and the corresponding bearing and the wedge block relocated all as will be readily understood.

Vhile I have herein shown and particularly described the preferred embodiment departing from the spirit of my invention,

but having thus described my invention I claim as new and desireto secure by Letters Patent the following I 1. In a car truck, he combination with car axles; of journal boxes supported upon the ends of said axles; and a side frame connecting the journal boxes, the bodies of said journal boxes being formed with displaceable trough bottoms having front, side and rear walls to permit lateral withdrawal of the axles from'the journal boxes, the box bodies having front and rear portions guarding against displacement of the trough bottoms.
